lpartnfient in the stovein which the appa'ra tus'f is? inserted, the stove -being provided with fhe' usua-l gratell. In the form shown Flg'. 1 theapparatus consists of'a. pan 12. which. forxns a. supliort for the same, said pan r'esting"upon the grate 11'. The 'plate 14 is secured to the pan adjacent-one of its .rends,-*the pa;n'being formed with upstanding lugs- 15., bolts paissing'throngh said lugs and' saidplate; This -constr uction'lis designed for the bur-nlng-of light oil, the construc- Y tioiishownin Fig. 9 being designed foruse' .in the burning-of heavy oil, being more adapted -.''for furnaces. In" the form shown in Figs-l, 6 and -8 thedntegial -flange 14 'of -the'frusto-conical 'ho'od 17 is attached to I the l1igs1l5,-this hood being provided with 30 an =interiorly formed lug. or support 19. This suppor'tis provided with passages 2Q and 21, the passageQQ which is disposed. longitudinally of; the support communicating with the chamber 22 of the hood; The 5 oil supply pipe 27 is screwed into the hood, said-pipe comn'iunicating with the, passage" 21. The tank for the supply oioil may he located at 'a point remote from the burner; that 'is,- the same may be arranged on the-9o exterior ofthehouse in which the'burne'r is 1ised.. gDisposed at a point adjacent -said tank and between said tank and the. burner is cylinder 28 which removes. any objec-- tionable'matcrial from the oil. the cylinide'r containingany suitable means for herforming the above function, the precise construction of which is not concerned in the present invention. The supply of oil in the j'al'v'e; as well 'as thevalve hereinafter men- 'tl0lld is pr 0\"ided with the dial shownin Fig. 4 in-ordcr th'atthe supply may be ace'urately regulated. The steam generator 32 issupported adjacent one edge of thc fpan, 165' being spaced from the same as shown in- Fig. '3. The generator is connected to the.

' pine-33 which pass'esih-rough the plate 14 and snpplies water to the generatmg theflow of wateribeing controlled by the valve The water enters the generator and when -steam is'generatcd the same passes pipe is 3 regulated. by the valve 30. This 10c- If p I paapyra, s

through th.- steam the pipe 38 the support 19 and;- which communicates with. the passage 20. This-pipe'is connect' ed ,to the drain-39, a valved being arranged' ir said connection, this valve being -manipulatedto'allow a'certain portion of the steam generated inthe steamgenerator to escape and to thereby indirectly re ulate the supply. fsteam; passinggthrou'g h the passage 20, commingling with the" oil, the mixturepassingout of the passage into theflared terminal of said .passa'g'e, being 'sprayed upon the pan.

' The opening 0 at the rear otftile, conical hood 'isclosed' by the damper shown in de-- tail in Fig. 7, thisdamper being utilized [whenflthe fire is being start-ed The damper I consists of a plate 41 which is rotatably. supported by the hood, the slot 42 being ad-.

justed with respect to "the opening 40- to regulate the supply of-"air: The-plate is" formed with thearcuate slot-43,.an adjust-' ing screw 44 locking the plate in any-dc ired position, fih e'0peni th s n' .in proper relation witht -da ng r (if ti damper being-accidentally rotated I In operation .water is supplied tofthe'gena eratorBQ, fire being started in, the pamthe damper plate beingrotated to open the end of the hood, andsteam generated. "When steam is generated the oil inlet, valve -is opened and, oil supplied to the pipe 27, this;

oil rising through the. passage 21' 'tothe passage 20. The steam is admitted to'the passag'e 20,-the on: thus being sprayed on thepan 12,-the oil ,and steam being commingled with air, thereby forming a perfect mixture for the burner. Attention is called to 'thefactthata perfectmixture oto l and steam is secured, the combined oil and steam being forced under pressure creating a suctionf which commingles air with the mixture thus securing a perfect fuel;

It will be ;noted that various changes may be made'in the arrangement of the steam and oil pipes without departing from the spirit of the-invention and that the same may be readily 1 placed in furnaces and stoves, the fire boxes ofwhich vary in size.

*As illustrated in Fig. 11 the frusto-conical hood member is formed integral'witht e outstanding plate 14 which plate 14- is rigidly secured to thepan 12 and supported thereby, In order to lockthe entire device against shifting and to further provide means whereby the oil burner maybe attached to stoves of'varying' sizes, the slidable plates 18 are secured to-the plate 14 and are adapted to be rigidly secured-thereto. The slidable plates1'8 are provided with longitudinal slots 48, suitable locking means cooperating therewith to hold the said plates in position. 'The locking members 51 as illustrated in detail 'in Fig. 10 areadapted to engage a portion of the stove, the same alsoadapted to hold the slidable plates 18 rigid withresp'ect to the "plates 14; From 51 prevent the entire device from shifting with relation to'the stove-or furnace to The form shown in Eig'sf9tand 11 is-designed.- for use with heavy oil, mention'beis slightly-less than thepressiire at which .-communicate, and" a; passage 251being .disposed longitudinally of the support communicatinggwiththe chamber 22 of thehood.

%with the passage 20' the nozzle being formed. with-ayfiared delivering end- 541 which project's beyond""the hood." In this-form the steam generator"will1' have a"w'ater supply pipe 55 whichis controlled'by the valve 56, the'steam generated passing through there- 'turnpipe 5'1 and to the coupling 59. "The valve "connecting said coupling. with the this coupling with'the'steam passage 21" and has a check valve located' therein said check valve discharging toward the steam 'passage'2l". The .oil -Fs'upply pipe 62 comlmunicates with the passage 20" said supply of oil being regulated by the valve 63 ,which is disposed between the tank'which'receives" the residue and the. burner; It will be noted steam are' formed reversed with respect to those shown in' the form for burning the lighter oil, the gonst'ruction beingpractically the same -with the exception of-the addition of'the nozzle 52.

: It will be notedthatwarioils'other changes may be madein the. arrangement of the oil and; steam supply pipe for the burning or various grades of 'oil, the: structure shown for the burning of heavy oil which the nozzle is' employed being particularly adapted for use in connection with 'furnaces or engines w- The many advantages of a construction of this character will be, clearly apparent and it will be noted thatthe' same maybe easily and economically manufactured and that the device may be readily positionedzwithin stove openings whichvary in size. T'it will also be noted that .thelstructure is such that the various changes inthe supplying ofoil and. steam may be' eficted without materially alteringthe constructing hood 7 Having thus described. the invention wha is claimed is 1.
